WINDING AND SLITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 577,865, dated March 2, 1897.

Application filed October 29, 1895. Serial No. 567,311. (No model.)

T0 at whom it may concern:

Be it known that I, CHARLS KOEGEL, a citizen of the United States of America, residing in Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in WVinding and Slitting Machines, of which the following is a specification, reference being had to the accompanying drawings and letters and fig ures of reference marked thereon.

The object of my invention is to provide a machine by which paper or other material may be closely wound and formed into a thoroughly-compact mass and with which the material may be cut during the process of rolling and compacting, producing a series of rolls the sides of which will be uniform.

My object is, further, to provide a device wherein the cutting operationwill be performed after the material is Wound in part upon the spool, thus avoiding all inaccuracies resulting from cutting beforethe material reaches the spool, thus avoiding the formation of a completed roll having uneven sides and avoiding defects resulting from the unequal stretching of the strips after separation.

My object is, further, to provide a device in which the cutters will at all times be automaticallymaintained in the same relative position to the material.

My object is, further, to provide a device for rolling and cutting wherein the position of the cutters with reference to the material is regulated and controlled by the roll of ma terial itself.

My object is, further, to provide a machine wherein disks of closely-wound paper or other material may be formed which will be uniform and accurate, and also to produce an improved machine wherein a better result is attained than has been heretofore reached.

I accomplish the objects of my invention by the construction herein shown.

The construction and operation of my device may be briefly described as follows.

Mounted in a suitable frame is a spool-shaft carrying a spool upon which the material is compressed or tightly rolled and wound and at the same time cut in any desired width or widths, the cutting operation being performed after the material is in contact with and in part wound upon the completed roll. Before being operated upon the material is supported upon a shaft and may be located at any convenient point, preference of course being given to mounting said shaft in the machine-frame. The material is conducted from the supply-roll over a guide roll or rolls and thence tothe presser-roll. Thepresser-rollis mounted in boxes having sliding movement in the frame, so thatas the size of the roll in process of formation increases in diameter the presser-roll will be lifted thereby.

The cutters consist of rotary disks mounted upon a revolving cutter-shaft, which shaft is mounted in sliding boxes, which also move away from the roll in process of formation as its diameter is increased, this movement being controlled by the roll in process of formation operating upon a roll in contact therewith.

I prefer that the presser-roll act as a regulating or controller roll for the cutter-shaft, but it will readily be seen that an independent controller-roll may be employed, it being operatively connected with the sliding boxes in which the cutter-shaft is mounted in the same manner as illustrated by me with reference to the presser-roll.

Referring now to the detail of construction, a suitable frame is provided, having vertical side posts A, which posts are provided with suitable ways in the front portion thereof, in which ways are mounted the upper sliding boxes 0 and the lower sliding boxes D. The boxes B, in which the spool-shaft E has bearings, are fixed in position upon said posts.

A main driving-shaft 0 is suitably mounted in the portion of the frame at the rear of the posts, which shaft is provided with fast and loose pulleys in the common well-known manher. A clutch p of any convenient form of construction is arranged upon said shaft to engage and drive a spur-gear 0, also mounted upon said shaft. The main driving-shaft is provided at its opposite end portion with a pulley X, carrying abelt which passes over a pulley V, mounted upon the cutter-shaft G, and thereby causes the cutter-shaft to revolve; and to keep this belt taut at all times I prefer to employ the common form of idler shown in the drawings in Fig. 5 and an arm 1 pivotally mounted and provided at one end with an idler-pulley Y and at its opposite end with a weight g, thus avoiding danger of the stopping of this belt and insuring the rotation of the cutters and the consequent perfect cutting operation.

The spool-shaft E is provided with a spurgear M and receives motion from the spurgear 0, mounted upon the main drivingshaft, through the operation of an intermediate spur-gear N, mounted upon a suitable stud upon the frame, so that the cutters may be put in motion first and then through the operation of the clutch the spool-shaft may be caused to revolve, this being desirable to prevent danger of tearing the material, which might result if both the roll of material and cutters started at the same time, and as the cutters might be slightly irregular a nicer adjustment of them to the material can be made when they are controlled independently of the material.

The rear portion of the machine is provided with suitable bearings, in which is mounted a shaft L, carrying the supply of material to be operated upon. The upper portion of the posts at the rear are provided with suitable hangers 76, supporting boxes in which a shaft carrying a guide-roll J has bearings.

The cutters consist of independent disk blades, mounted upon the cutter-supporting shaft G, and collars, rings, or other separatin g devices are arranged between their faces to give the requisite separation.

The spool-shaft E is provided with a spool I, mounted thereon, upon which spool the material is wound.

Z is a pulley mounted on the supply-roll shaft L, upon the periphery of which pulley a shoe bears, the tension on the pulley being produced by a weighted lever or a spring bearing the shoe toward the pulley.

U are stay-rods or braces extending from side to side of the frame.

At each side of the frame and mounted at the top thereof are sprocket-wheels P, having their central openings threaded or by preference being mounted upon threaded nuts and connected by a sprocket-chain Q, and secured to oneof these sprocket-wheels is a spur-gear R. A like spur-gear is mounted at one side on a suitable support, the teeth of which gear mesh with the teeth 011 the bevel-gear R. The hand-wheelz'is mounted upon the shaft carrying the bevel-gear T, so that a revolution of the hand-wheel will operate through the medium of the bevel-gears to cause one sprocket-wheel to be revolved and through the operation of the sprocketchain cause the other sprocket-Wheel to be revolved to the same extent.

The rods S and S are exteriorly threaded to engage the threads in the nuts or interior threaded portion of the sprocket-wheels. It will now be seen that if these rods be restrained from turning the revolution of the sprocket-wheels will cause them to be moved up or down, dependent upon the direction of revolution of the sprocket-Wheels. These rods are each provided with a longitudinal slot or groove, and their lower ends pass through an offset or shoulder 2 on the back side of the boxes C and are prevented from revolving therein by a set-screw or key entering the slot, so that if the movable boxes C be fixed in position the rods S would be free to move vertically in either direction through the opening in the offset 2 and would be prevented from rotating therein. The upward movement, however, in this olfset is limited by a nut on the end of each' rod, and the downward movement is limited only by the length of the threaded rods. The sliding boxes 0, however, are free, as before stated, to move up and down in suitable ways in their supporting-frame,carrying with them, of course, the presser and regulating roll F.

Racks 0, having teeth upon their inner edges, are secured at their upper ends to the boxes 0, the frame being provided with suitable ways for the racks. The fixed boxes B have mounted upon their inner faces spurgears a, the teeth of which mesh with the teeth on the racks 0, so that the moving of the sliding boxes 0 either up or down will cause the spur-gears a to revolve in a direction dependent upon the direction of the movement of the sliding boxes 0.

The sliding boxes D, which carry the cutter-shaft G, have secured to them and projecting upwardly therefrom racks d of like construction as the racks secured to the boxes 0, as before described, so that the revolution of the spur-gear or, caused by the upward or downward movement of the sliding boxes 0, will give a like extent of movement, but in reverse direction, to the boxes D.

To provide for the proper adjustment of the cutter-blades with reference to the material being operated upon, the racks d, mounted upon the sliding boxes D, instead of beingimmovably fixed thereto are adj ustably mounted thereon by the employment of adjustingscrews 3, which have threaded connection with the offsets or lugs t on the back side of the sliding boxes D. The racks d have secured to them and projecting toward the center of the frame-posts arms or offsets 5, having forked openings in their ends to receive the head of the adjusting-screw 3, which is provided with an annular recess, so that a part of the head is above and a part below the arms 5, and by turning the set-screws 3 in the desired direction the relative position of the knives with reference to the spool may be varied.

The roll J is a guide-roll in the sense that it serves to guide the paper or other material in its passage from the supply-roll to a position where it may be led conveniently tothe location where it is to be operated upon.

The roll F is a regulator or controller roll in the sense that it by contact with the material as it is wound upon the receiving-spool determines the position of the cutters with reference to the material, for it will readily be seen that as the material is wound upon the spool the diameter of the spool is increased, the roll F thereby raised or moved outwardly, and through the mechanism before described the cutters are carried away from the spool,

so that the roll F serves as a guide or controller to determine the position of the outters with reference to the material.

The material to be operated upon is carchine upwardly over an idler or guide-roll J and downwardly in front of the roll F and wound upon the spool sufficiently to cause it to bight. The hand-wheel t' is then turned carrying the roll F, until the roll F rests upon the material and is sustained thereby, so that at that time the nuts upon the ends of the threaded rods S will not bear against the offof the boxes 0 will, through the operation of the racks c and d and the intermediate spurgear a, operate to carry the sliding boxes D upwardly, thereby bringing the cutter-shaft will be in contact with the material upon the spool, at which time, if the cutter-blades do not occupy the desired accurate position, they may be adjusted upwardly or downwardly by the adj ustin g device operatively arranged be tween the sliding boxes D and the racks d. The machine being now started, the roll will increase in diameter. The roll F will thereby be moved away from the spool-shaft, causing the sliding boxes 0 to move upwardly, carrying their racks with them, the spur-gear a being thus caused to revolve in a direction to carry the racks cl and the sliding boxes D with them downwardly, thus carrying the cuttershaft G and cutters away from the spool-shaft, the threaded rods during this operation remaining at rest and projecting through the offsets co to an extent dependent upon the upward movement of the sliding boxes 0, caused by the upward movement of the roll F, caused by the increasing size or diameter of the roll being formed.

When it is desired to remove the finished roll or rolls from the spool-shaft orfor any purpose to maintain the roll F and the cuttershaft separated from the spool-shaft or material, it simply becomes necessary to turn the hand-Wheel i in a direction to cause the threaded rods S to move upwardly until the nuts upon their ends engage the ofisets on the boxes C, and a continued turning of the hand-wheel will result in moving these boxes upwardly and with them the roll F away from the material, where they will remain until the hand-wheel be again turned to place the parts in the desired operative position, the cutter-shaftbeing moved in each instance a like distance, but in reverse direction.

lVhen the parts are in position and so adjusted that the cutters will cut through one thickness of material, the machine may be started, and as the material is wound upon the spool it is cut into strips dependent upon the distance of separation of the cuttingblades, and at the same time it is wound with a degree of firmness, closeness, and solidity ried from the supply at the back of the rnain a direction to lower the sliding boxes 0,

sets 2 on the sliding boxes 0. The lowering G to a position where the edges of the cutters dependent upon the pressure of the roll F upon the material. The weight or pressure upon the material may be varied as required by substituting other rolls of different weight. It will of course be readily seen that the pressure and guide roll might be made separate, 1'. e. two rolls be employed, one for the purpose of giving the requisite tension or pressure and one as a guide and operatively connected with the intermediate adjusting or guiding mechanism, without departing from my invention. I prefer, however, that one roll be used both for pressure and regulator.

The winding or rolling of the material be fore it is cut insures perfect accuracy in the completed roll, while if the cutting operation be performed before the material is wound perfect registry at the edges will not result. At least inaccuracies are liable to occur, which will leave the sides of the finished roll uneven.
